Gary is the project manager for his organization. He is working with the project stakeholders on the project requirements and how risks may affect their project. One of the stakeholders is confused…

Limiting the impact to only project costs is too narrow - risks can affect scope, schedule, quality, and other objectives as well.

Describing risk as an event 'within the project execution' incorrectly restricts it to execution phase and omits conditions, which are also a form of risk.

According to the PMBOK Guide, a project risk is formally defined as an uncertain event or condition that, if it occurs, has an effect on at least one project objective such as scope, schedule, cost, or quality. This definition is deliberately broad, covering both threats and opportunities across all project objectives, not just a single dimension.

Using 'unknown event' rather than 'uncertain event' is inaccurate - risks are known uncertainties, not unknown unknowns, and limiting impact to scope alone is too restrictive.
